ความเห็นบรรณาธิการ

I use both regularly and for very different reasons. When I need a quick wireframe to share with a client, Whimsical makes it look polished in 10 minutes. When I need a detailed ERD or AWS architecture diagram, diagrams.net has every shape I need for free. The honest answer is most people should try Whimsical first — if its focused feature set covers your needs, the design quality is worth it. Fall back to diagrams.net when you need more technical depth.
